Hello, Sennheiser headphones may be worth looking into. They make an excellent line of headphones, and they have been around a very long time. Try a search for the HD series.
My personal choice for closed, lower-moderate weight and comfort, while not a maximum performer but has good bang-4-the-buck: Beyerdynamic DT 231.
Edit: Some great information and reviews here: HeadRoom - right between your ears . Many kinds, large price range. The DT231's are reviewed in at least two sections, Earpad Headphones and Sealed / Noise Canceling.
